ImageMagick has infinite loop when writing IPTCTEXT leads to denial of service via crafted profile
A crafted profile contain invalid IPTC data may cause an infinite loop when writing it with `IPTCTEXT`.

ImageMagick has uninitialized pointer dereference in JBIG decoder
An uninitialized pointer dereference vulnerability exists in the JBIG decoder due to a missing check.

ImageMagick: Heap Buffer Over-read in WaveletDenoise when processing small images
A heap buffer over-read vulnerability occurs when processing an image with small dimension using the `-wavelet-denoise` operator.

ImageMagick's failure to limit the depth of SVG file reads caused a DoS attack
Using Magick to read a malicious SVG file resulted in a DoS attack.

ImageMagick has heap buffer overflow in WriteXWDImage due to CARD32 arithmetic overflow in bytes_per_line calculation
A 32-bit unsigned integer overflow in the XWD (X Windows) encoder can cause an undersized heap buffer allocation. When writing a extremely large image an out of bounds heap write can occur.

ImageMagick: META reader memory leak in the APP1JPEG input path
ImageMagick contains a memory leak in the META reader when processing the `APP1JPEG` input path.

ImageMagick has stack write buffer overflow in MNG encoder
A stack buffer overflow vulnerability exists in the MNG encoder. There is a bounds checks missing that could corrupting the stack with attacker-controlled data.

```

ImageMagick releases an invalid pointer in BilateralBlur when memory allocation fails
The BilateralBlurImage method will allocate a set of double buffers inside AcquireBilateralTLS. But the last element in the set is not properly initialized. This will result in a release of an invalid pointer inside DestroyBilateralTLS when the memory allocation fails.

ImageMagick: Heap overflow in sun decoder on 32-bit systems may result in out of bounds write
An Integer Overflow vulnerability exists in the sun decoder. On 32-bit systems/builds, a carefully crafted image can lead to an out of bounds heap write.
